MORITZ, SWITZERLAND, A CORPORATION TRANSPORTATION OR PRESSURE VESSEL FOR GASES Application filed January 11, 1980p8eria1 No.

The present invention relates to containers for trans orting liquefied gases particularly those which can be liquefied cm with dltliculty. The invention has for its 0 ject to rovide a container for liquefied ases in W 11011 the inner vessel for the liqui is suspended and insulated from the outer jacket of the vessel in such manner as to reduce the transfer of heat (from external sources into the liquid to a minimum.

More particularly it is an object to pro vide a container comprising inner and outer vessels separated by heat insulating material and provided with suspension means for the inner vessel which support the latter in a mechanically rigid manner with relatively little conduction of heat.

A more specific object of the invention is to provide a means for sus ending the liquidcontainer in heat insulating relation to the outer jacket of the pressure vessel, comprising a chain so constructed that the transfer of heat from one link to another is substantially restricted.

The present application is a continuation in part of m co endin application, Serial No.232,924,hled ovem er12,1'927.

Other ob ects of the invention will in part be obvious and will in part appear hereinafter.

The invention accordingly comprises the features of construction, combinatlon of elements, and arrangement of parts, which will be exemplified in the construction hereinafter set forth and the scope of the application of which will be indicated in the claims.

For a fuller understanding of the nature and objects of the invention reference should be had to the following detailed description taken in connection with drawing, in which:

Fig. 1 is 'a partly sectional view through a container constructed in accordance with the invention; v

Fig. 2 is a fragmentary sectional view illustrating one form of the linked the chain shown in Fig. 1; and

Figs. 3 and4 are views similar to Fig. 2, illustrating modifications of the links.

Referring now to the drawing, 1 designates manner from the outer jacket pressure vessel, in spaced relation to said the accompanying 42o,o4, and in Germany November 1a, 1926.

a liquid container, which is suspended by means of chains 2 in a mechanically rigid or shell 3 of a jacket, the space, between the container and jacket being filled with a suitable heat-insulating material 4. The container is shown in the present instance portion with suitable inlet and outlet tubes 5 and 6, which are embedded in insulating material within an extended portion 7 of the top of the jacket. This arrangement serves the double purpose of protecting the tubes against the influence of outside temperatures and providing a convenient terminus for the pipes that is advantageous in transportation.

The chains 2 are composed of a plurality of provided at its upper K engaging links so connected to each other as to minimize the transmission of heat from one link to another. In order to minimize the rate of conduction of heat along the chain from the exterior, means are associated with the engaging portions of the connected links which offer greater resistance to the norm-a1 heat conduction. In the formshowninFigQ, a heat-insulating member of ring form is interposed between the engaging surfaces of the successive links, so that the links do not make direct contact with each other at anypoint. In Fig. 3 the interposed insulating member is omitted but an arrangement is used that reduces the amount of surface in contact between links. In this form a recess 9 is formed in the surface of one link, the radius of arc of said recess being less than the radius of the intersecting surface of the contacting link, so that the links contact with each other only at two points, one at each side of the recess 9. In the modification shown in Fig. 4 the links are in direct. contact with each other, but in this case one link is formed with asharpedged ridge 10 which engages the companion link only at a single point. If desired, both links may be provided'at their intersecting portions with ridges so that the ridges cross each other and insure point contact.

Since certain changes may be made in the above construction and different embodiments of the invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanyingdrawing shall be interpreted as illustrative and not in a limiting sense.

Having described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. Apparatus for transporting liquefied gases, comprising, an outer jacket, possessing a desired degree of'operative rigidity, a liquid-container within said jacket completely encompassed in s aced relation thereto, insulating material disposed between said liquidcontalner and jacket, and metallic chains suspending said container from the walls of said jacket, said chains being embedded in said insulating material, and comprising links havin only point contacts with each other where y transmission of heat through said chains is minimized.

2. A. container for transporting and conserving liquefied gases, comprismg inner and outer vessels having the intervening. space filled with heat insulating material, said outer vessel having a wall of desired operative rigidit formed with outwardly extended portions, metallic chains having connectedlinks traversing said insulating material anchored in the outwardly extended portions of said outer vessel dis osed to maintain said space in its operative cm and secured to the wall of said inner vessel, and means associated with the engaging'portions of connected links for reducingthe normal heat conduction between said links. 3. A container for transporting and conserving liquefied gases, comprising an inner vessel for holding liquefied gas and an outer supporting jacket disposed in spaced heat insulating relation without direct'contact with said inner vessel, metallic chains anchored in the wall of said outer jacket and secured to the wall of said inner vessel whereby the space between said inner vessel and outer jacket is maintained in operative form, and means associated with one or more of said chains for obstructing the conduction of heat between any two consecutive links of said chains.

4. A container for transporting and conservin liquefied gases, comprisin an inner vessel or holding liquefied gas mil an outer sgporting jacket disposed in spaced heat in s ating relation without direct contact with said inner vessel, metallic chains anchored in the wallof said outer jacket and secured to the wall of said inner vessel whereby the space between said inner vessel and outer jacket is maintained in ofi'rative'form, and

engaging means on one of said chain which is formed to obstruct the flow of heat and shaped to have substantially point contact with the adjacent link whereby the heat conduction to the inner vessel is minimized.

5. A container for transporting and con- Leeann? servin liquefied gases, comprising an inner vessel or holding liquefied gas and an outer supporting jacket dlsposed in spaced heat insulatin relation wlthout direct contact with sai inner vessel, metallic chains anchored in the wall of said outer jacket and secured to the wall of said inner vessel whereby the space between said inner vessel and outer j ac et is maintained in operative form, the engaging portion of one link of said chain having an edged ridge adapted to contact with the enga 'ng portion of the connected link whereby t e heat conduction to said inner vessel is minimized.

6. A container for transporting and conserving liquefied gases comprisin an outer jacket having a desired degree 0 operative rigidity, a container disposed within said jacket and spaced therefrom to provide an intervening space between the walls of said container and jacket which substantially completely' encompasses said inner container, metallic chains for suspending said container from the walls of said jacket in a relatively fixed position with respect to said jacket, and

means for obstructing the transmission of heat between consecutive links of said chains.

In testimony whereof I have signed my name to this specification.
